Is Your Society Good for (Biological) Fitness?
Connor Wood: Creatures that survive long into old age but never have offspring are not winners of the biological game. If our model is at all accurate, human beings’ emotional investment in our communities and their rituals largely hangs on whether those communities deliver the full package of biological goods. When we see that our fellow tribe members are well-fed, wealthy, and long-lived, that’s great. But if our healthy, well-off compatriots seem to have trouble easily finding mates or starting families, we might subconsciously start losing faith in the tribe anyway.
